Bently Nevada 330104-00-05-50-02-00 3300 XL 8mm Proximity Sensor Probe

The Bently Nevada 330104-00-05-50-02-00 is a 3300 XL 8mm proximity probe featuring a 5.0-meter total length and specialized connector protectors. This industrial-grade eddy current sensor provides precise non-contact measurement of shaft vibration and position, facilitating advanced predictive maintenance for critical rotating equipment.

Precision Machinery Condition Monitoring

The Bently Nevada 330104-00-05-50-02-00 belongs to the renowned 3300 XL 8mm series, representing a gold standard in eddy current sensor technology. This proximity probe measures static (position) and dynamic (vibration) distances between the probe tip and the observed target material. By converting these physical displacements into proportional voltage signals, the sensor allows for the continuous tracking of shaft vibration and axial position. Consequently, plant operators gain the ability to monitor critical tolerances in high-speed rotating machinery with extreme accuracy.

Detailed Technical Configuration

The specific alphanumeric code 330104-00-05-50-02-00 defines the physical and electrical characteristics of this sensor. Each suffix indicates a tailored engineering choice:

Probe Model: 3300 XL 8mm Proximity Probe
Unthreaded Length: 00 mm (Fully threaded body)
Overall Case Length: 05 mm
Total Length: 5.0 meters (50 decimeters)
Connector Type: Miniature coaxial ClickLoc connector with connector protector
Agency Approval: None specified (Standard version)
Probe Tip Material: High-performance Polyphenylene Sulfide (PPS)
Linear Range: 2 mm (80 mils) beginning at approximately 0.25 mm (10 mils) from the probe tip

Operational Reliability and Durability

Industrial facilities operate in demanding environments; therefore, Bently Nevada constructs these probes to withstand chemical exposure, high pressure, and temperature extremes. The 3300 XL system features a patented Tip-to-Case seal that effectively prevents moisture and oil from infiltrating the sensor internals. Furthermore, the Gold-plated ClickLoc connectors ensure a secure, corrosion-resistant electrical path back to the Proximitor Sensor. Because this hardware integrates seamlessly with the 3500 series monitoring racks, it provides a robust foundation for any comprehensive Asset Condition Monitoring (ACM) strategy.

Targeted Industrial Applications

Maintenance teams typically deploy the 330104-00-05-50-02-00 on critical turbomachinery where even minor shaft deviations can lead to catastrophic failure. Common applications include:

Monitoring radial vibration in fluid-film bearing motors and generators.
Measuring thrust position in centrifugal compressors and steam turbines.
Tracking eccentricity and differential expansion in large-scale power generation units.
Capturing Keyphasor signals for phase timing and rotational speed measurement.
